چکیده

Desalination of seawater is of great importance due to the increasing global demand for freshwater.This article outlines a proposed method for desalination and water distribution, designed to leveragethe principles of water vapor behavior to evaporate seawater or salty lake water, condense the vapor,and produce distilled water for distribution. A case study was conducted in the northern and southernregions of New Zealand, specifically for the conference in question, leading to the decision to choosea case study within this country. The study aims to develop formulas for the transfer of water vapor indesalination and its transport in pipelines. Basic formulas of continuity and momentum are utilized,and after simplification, the study seeks to enhance the accuracy and efficiency of pipe simulation byconsidering the fluid to be incompressible. The study's findings suggest that increasing the sourcetemperature can significantly boost the production rate, and using a larger diameter pipe can be morecost-effective in terms of production rate and vapor temperature in the condensate section. Regardingthe specific data from the study, for the north of New Zealand, a one-meter-diameter pipe can transmit۵,۰۰۰ cubic meters of distilled water per year, while a two-meter-diameter pipe can transport ۲۴,۰۰۰cubic meters of water. In the south of New Zealand, the data shows that a one-meter-diameter pipecan transmit ۷,۰۰۰ cubic meters of distilled water per year, and a two-meter-diameter pipe cantransport ۳۲,۰۰۰ cubic meters of water.
